Frost indeed, but for those late flowering phenos it deosn't seem to be a problem in their homeland. Those late flowering plants are said to produce the best charas. Same in Chitral valleys, harvest start in August, and can go up to December/January for some phenos.

I look forward your Mazari line Mriko, big up bro! It would be so cool to cross our things next years and revive the MIS genetics.
Are yours F2? Still have original imported ones too?
